Frequently Asked Questions

What is pentaerythrityl tetracaprylate/tetracaprate used for?

Pentaerythrityl tetracaprylate/tetracaprate (CAS 68441-68-9) is the pentaerythritol tetraester of caprylic (C8) and capric (C10) acids, supplied as a light emollient ester. It is used as an emollient, a low-viscosity spreading agent and carrier for actives and pigments, and a lubricating ester base in personal-care formulations.

What is pentaerythrityl tetracaprylate made from?

It is produced by esterifying pentaerythritol with a blend of caprylic (C8) and capric (C10) fatty acids, yielding the tetraester with molecular formula C37H68O8. These medium-chain acids give the ester its light, low-viscosity character.

What industries use pentaerythritol esters?

Pentaerythritol esters are used across cosmetics and personal care (as emollients and pigment carriers), synthetic lubricants (as ester base stocks), and coatings/resins. This particular C8/C10 tetraester is positioned mainly for skin-care and personal-care formulating as a light emollient.

What is the CAS number for pentaerythrityl tetracaprylate/tetracaprate?

It is supplied under CAS 68441-68-9 with molecular formula C37H68O8. An HS code is not listed on the standalone record; confirm the appropriate tariff line for fatty-acid esters with your customs broker.
